APPENDIX C
SAFETY DATA SHEETS

C.1 General

C.1.1 All work places must have SDS's of each of the dangerouschemical substances handled in it and must be permanently available for all workers involved in their use, so that they can have immediate information in order for them to establish preventive or corrective measures within their work place.

C.1.2 SDS's must be in Spanish language. Its format is free and must contain, in an orderly manner, as a minimum, all information that is established in this appendix.

C.1.3 Information must be reliable, so that its normal use produces an adequate attention for human life and health care or in order to control an emergency.

C.1.4 There should not be blank spaces. If the required information is not applicable or is not available, NA or ND contractions should be used depending on the case, and at the bottom of the SDS, reference must be made on the source of the information contained on them.

C.1.5 SDS's must be actualized in those cases where new data is obtained on the dangerouschemical substance.

C.2 Contents of the SDS's.

C.2.1 Title: Safety Data Sheet. SDS and the name of the substance. On each and all pages of each SDS the name of the substance must appear on the upper right corner.

On dangerous components: name and percentage of the dangerous components, including their identification and classification of the degree of risk, according to what is stated on III.1 and III.2 of this Appendix.

SECTION V. Risks of Fire or explosion:

V.2 Specific personal protection equipment to be used on fire fighting work.V.3 Special procedure and cautions to be taken during a fire fighting.V.4 Conditions that may drive to another special risk.V.5 Combustion residues that may be health hazardous.

IDLH value. As a reference, the Pocket Guide to chemical Hazards may be utilized.

Note: An additional source of information may be utilized for c) and d) indicating the source.

III.2 Classification of the degree of risk.

Enter the selected system that may be rhomboidal or rectangular model or any other. In the case of other, it must be authorized by the General Directorate of Labor Safety and Hygiene indicating the justification as well as the health, flammability, reactivity, special risks values, and in its case, the necessary personal protection equipment.

III.3 About risky components.

When the properties of the mixture components change it will be reported as a final product, and in the case that the individual properties of the components do not change, they will be individually blotted out, entering the chemical names of all the components of the substance that has been determined as toxic and which percentage be larger than or equal to 1% of the mixture. When the latter is secret, report the chemical group.

SECTION IV: Data of the physical and chemical properties that most be noted down:

IV.1 The corresponding values according to their physical and chemical properties.

V.1 The recommended extinguishing agents and, in due case, the forbidden ones.V.2 The personal protection equipment that must be used for fire fighting.V.3 The steps for the procedure for fire fighting and special precautions that must be taken.V.4 Conditions that may drive the dangerouschemical substance to generate a special risk.V.5 If there are generation of products during combustion, such as: health hazardous gases, smoke or noxious vapors.

SECTION VI. Reactivity data that must be noted:

VI.1 If dealing with a dangerouschemical substance either stable or unstable.VI.2 If the chemical substance shows incompatibility with other substances, having to specify which are these substances.VI.3 If the chemical substance may generate decomposing dangerous products and which are these.VI.4 Which conditions must be avoided in order not to generate a polymerization risk from the dangerouschemical substance.VI.5 Other conditions to be avoided while using the dangerouschemical substance in order to avoid its reaction.

SECTION VII. Health risks:

VII.1 Note down the most exceeding effects due to acute exposure to the dangerouschemical substance, through each way of intake to the organism.VII.2 Note down the most exceeding data due to the effects of chronic exposure to the dangerouschemical substance and indicate if it is considered carcinogenic, mutagenic or teratogenic.VII.3 Note down complementary information regarding mean lethal concentration and mean lethal dose. If additional information of developed laboratory tests on mean lethal concentrations and mean lethal doses, indicate so.VII.4 Emergency data and first aid procedures to be noted down.VII.4.1 ll procedures for the application of first aid for the different ways of intake to the organism;VII.4.2 Any other risks or effects on health;VII.4.3 The antidote, if there is one;VII.4.4 Any other important information for the primary medical attention and pertinent countermeasures.

SECTION VIII. Directions to be noted down for the case of leaks or spills:

VIII.1 All procedures and special precautions required for cases of leaking or spills.VIII.2 Mitigation methods for substance control.

SECTION XI. Data on information regarding the ecology that must be noted down:

XI. ndicate the behavior of the dangerouschemical substance when freed to the air, water or ground and its effects on flora and fauna.

SECTION XII. Special precautions:

XII.1 Note down all there is in relation to the precautions that must be taken in the handling, transportation and storage of the substance.
XII.2 If any additional special precaution is deemed necessary to be mentioned, do so.
